I need a A1 or A7 crank core. I really just need good flywheels, not worried about the rods or bearings. The crank is going to be stripped and stroked to run Yamaha rods for a race bike.
Thanks Dave

What bike, your A1R?

H1 or Jetski JS440 rods are dimensionally identical to A1/A7 rods apart from the centre-to-centre length and require only a new crankpin to be made if you don't have new A1 or A7 crankpins- no machining of the flywheels if you retain the stock 56 mm stroke. You gain some crankcase volume, which is beneficial for disc-valve engines, but do have to make spacer plates and fit longer cylinder studs, 172G0870 instead of the stocker's 172G0865.
I think I have a spare set of A1-R flywheels, mail me if interested.
